+GlusterFS is a scalable client-server network-attached storage file system. You can also check [https://docs.gluster.org/en/latest/Administrator-Guide/ official documentation] for more details.
 * Node: Server that provides storage space.
-* Trusted Storage Pool (TSP): cluster formed by one or more nodes.
+* Client: machine on which a volume is mounted
 * Brick: Minimum unit of storage (given by a file system exported by a node).
